The file for the graphene card can be found in the catalog, or by clicking here.

Try pushing really hard on the pencil

Try using mechanical pencils (the kind with refillable lead)

Let visitors know that they need to make a very dark line on the paper for this activity to work. It is ok if the LED bulb is dim. A dim light is not as much of a “wow factor,” but it’s still an indication that electricity is being conducted. We hope that one of these solutions will help you with this activity, and we’d love to hear your feedback in the comments section of this blog post– let us know what worked and what didn’t. Good luck with your final preparations!
